Abstract :
Synchrotron radiation (SR) can be applied as an excitation source of the accumulated photon echoes. The accumulated photon echoes of sulforhodamine 640 ( SRh 640) doped in polyvinyl alcohol film (PVA) was successfully observed by exciting the sample with the SR and employing the phase modulation method. When we used SR passed through a bandpass filter with bandwidth of about 13 nm, the photon echo decay curve was obtained with a time resolution of 133 fs. In addition, when the bandpass filter was removed, the field autocorrelation time of the SR beam decreased to about 3 fs
